摘要

高数量的磁极在电机允许减少定子和转子轭的径向厚度，从而重合金。如果允许频率随极数增加(恒速)，则可以保持功率水平。因此，高频率和高极数可以提高旋转电机的功率密度。提出的高频概念应用于设计1 MW电机，功率密度和效率目标分别为> 13kW/kg和> 96%。

A high-speed, high-frequency, air-core PM machine for aircraft application

High number of magnetic poles in an electric machine allows reduction in radial thickness of stator and rotor yoke and thus heavy alloy. If frequency is allowed to increase with pole-count (constant speed), power level can be maintained. Thus, high frequency, together with high pole count, can improve power density of rotating electric machines. The proposed high frequency concept is applied to designing a 1 MW motor, with power density and efficiency goals of > 13kW/kg and > 96%, respectively.
